ABSTRACT Diet composition and processing have a major impact on its utilisation by the animal, as is known from farm and pet animal species. This includes effects on energy and nutrient digestibility, the intermediary metabolism, and the intestinal microbiome, with all the resulting impacts. For laboratory animals, data is scarce on influencing factors

Detection and assay of polymorphism in reproductive gene loci in a commercial broiler breeder population for use in association studies [PDF]
A candidate gene approach has been adopted to determine if variance in reproductive traits in commercial broiler breeder stock can be associated with alleles of genes involved in reproduction. Alleles with favourable associations may be useful for marker

ABSTRACT Over recent years the use of yeast in feedstuffs has gained momentum due to novel developments in single‐cell proteins (SCPs). SCPs are considered a sustainable protein source, as their production enable to convert low‐value substrates (including industrial/agricultural wastes) into feed, with a related reduced environmental impact. This study

Iron requirements of broiler breeder hens
A study was conducted to investigate Fe requirements of broiler breeders. One-hundred-fifty-six Cobb 500 broiler breeder hens were individually placed in electrostatically painted cages at 22 weeks. The study was composed of an adaptation phase, in which hens were fed corn-soy-wheat bran diets until 35 wks.
